Batman: Arkham Asylum and Arkham City are the 2 greatest superhero games ever, and some of the best games of the last 10 years. Rocksteady have proven that they know what they're doing with this series, and have had 4 years to work on this game. They were given more time because they didn't want to rush the game out. They wanted it perfect. There's no doubt in my mind that this game will be the sequel that Arkham Origins tried to be but failed.
